To all whom it mag/concern,.-

Beit known that We, HENRY M. HARLEY and EUGENE U. GIBBs, citizens of the United States, residing at Gloucester City, in the 5 county of Camden, State of New Jersey, have invented'a new and useful Improvement in Calendering-Machines,which improvement is fully set forth in the following specification and accompanying drawings.

Our invention has reference to an improved construction of calendering-machine wherein the materialto be calendered is fed between presser devices arranged adjacent to and adapted to coact with a main drum or cylinder, the object being to produce in a simple and inexpensive manner a machine of this character which will not only effectively insure the thorough and even calendering of the material fed thereto, but one in which the mechanism thereof Will readily and quickly yield to compensate for any, unevenness in the material destined for treatment or for any unevenness in the periphery of the drum or cylinder or of the presser devices, thus successfully eliminating all liability of mutilating the material.

It comprises a suitable framework having mounted therein a main drum or cylinder, presser devices arranged adjacent thereto and at intervals around the periphery thereof, and means for automatically moving said presser devices into operative position with relation to said drum or cylinderl and for regulating the pressure thereon, as well as withdrawing the aid presser devices when necessary or desire It further consists of novel details of construction, all as will be hereinafter fully described, and pointed out in the claims.

Figure 1 represents a side elevation of a calendering-machine embodying our invention. Fig. 2 represents a front elevation thereof. Fig. 3 represents a vertical section of the same, taken on line s Fig. 2. Fig. 4 represents a detail view showing the main drum or cylinder, the presser device, and one form of auxiliary presser -device to be referred to. Fig. 5 represents a similar view showing another form of auxiliary presser de- 5o vice. Figs. 6 and 7 represent detail views of a modified form of our invention, certain of the parts being shown in section.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a suitable framework composed of two oppositely-disposed uprights or frames B, which may, if desired, be mounted upon any convenient base, (not shown,) said uprights being provided with a plurality of guideways 6o C, arranged in the present instance radially and adapted to receive therein journal-boxes D, which latter carry shafts E, whereon are mounted presser-rollers F. These rollers are located at convenient distances apart and are adapted when the machine is in operation to impinge the periphery of a main drum or cylinder G, carried in journal-boxes H, which for convenience are preferably arranged to slide freely in the same guideways in which 7o the journal-boxes D of one of the presserrollers F are carried, said drum or cylinder Gr being preferably provided with a soft or resilient covering Gr', which may or may not be used, according to requirements.

Each of the journal-boxes referred to is provided with suitable antifriction-bearings, as shown in dotted lines in Fig. l, and in addition thereto said boxes are each provided with a rod J, the outer free end of which sup- 8o ports a plunger or piston K, adapted to work in a cylinder L, secured to the outer extremity of each of the guideways C. E The cylinders L are preferably, but not necessarily, open at one end, and the plungers therein are properly and suitably packed, so that the inward movement'of the presserrollers F against the periphery of the main drum or cylinder G may be positively insured, said movement being caused by the 9o admission into the cylinders behind the plungers of a suitable fluid, as steam, compressed air, or other desired agencies, which enter said cylinders through ports M and pipes N, which latter lead into each of the cylinders, said pipes branching from a main supplypipe P, the latter having a controlling-valve Q thereon to govern thepressure admitted to the cylinders L.

R designates brackets or arms which proroe ject from the uprights B-in the present instance to the left thereof-and are designed to carry the roll of material destined for treatment, the same being guided over and between the first one of the presser-rollers F and the drum or cylinder G, then under an idler-roller S, thence between the next succeeding presserrollerF and the drum G, then under another idler-roller S, and continuing in this manner until the material has been passed under the last succeeding presserroller F at the upper left-hand corner ot' the machine, from whence it is rolled upon a reel T, which latter is carried in the free ends of arms U, pivotally secured to brackets V, projecting from the uprights B.

By the above construction and arrangement of parts the material to be treated is presented to the main drum or cylinder G at intervals around the periphery thereof, and the presserrollers F by reason of the cushion in the cylinders J, formed by the steam or other duid at the rear ends of the pl u n gers, and the pliant or resilient nature of the drum or cylinder G will readily yield to any unevenness in the material or to any obstacle of a foreign nature which might be accidentally carried in by the working parts, it being also noted that the free ends of the pivoted arms U will also rise as the finished material is wound upon the reel T to accommodate the increasing diameter of the roll, as will be apparent.

The presser-rollers F are situated on'all sides of the drum or cylinder G--that is to say, they are placed below, as wellha-s aboveand preferably disposed at equal distances around the same. The advantage of this disposition of the presser-rollers is that it gives an equal pressure upon the drum or cylinder and entirely around the same, and the drum or cylinder is practically supported or floated by said presser-rolls F, so l that although the drum or cylinder is mounted in journal-boxes I-I, yet there is practically no weight sustained by these journal-boxes in view of the fact that the drum or cylinder is supported and its weight sustained by these presser-rollers.

In Fig. 4 we have shown a detail view of a construction substantially similar to that above described, except that anl additional auxiliary roller F is employed, the same being interposed between the iirst presser-roller F and the drum or cylinder G. The said roller F', as well as the first presser-roller F, is of chilled iron and is used on the first pressure nip for the purpose of crushing any material roller F, the same being carried in journalboxes D', adapted to move in guideways C', which latter may be secured to or made integral with the uprights or fram es B. The guideway C' is arranged at an angle to the guideway C and presser-roller F, with which it coacts, and the puter end thereof is provided with a removably-secured cross-bar W, having a threaded opening therein to receive a screw X, carrying a hand-wheel, said screw bearing upon the journal-boxes D and so moving and keeping the auxiliary roller F2 against the presser-roller F.

In Figs. Gand 7 we have shown a modified form of our invention, wherein auxiliary plungers K and cylinders L" are employed to simultaneously withdraw the presser-rollers from contact with t-he main drum or cylinder'G. These auxiliary cylinders are arranged adjacent to each of the cylinders L and have therein the rods J" and attached plungers K, said rods being secured to or being made integral with yoke-straps S, which embrace or surround the axes of each of the presser-rollers F, but in such manner as not to interfere with their free movementwithin the guideways C. The outer ends of each of the auxiliary cylinders' L" are preferably open, and their opposite ends are provided with ports M" to receive pipes (not shown) by which steam, compressed air, or other fluid is admitted into the cylinders when desired,thus causing the plungers therein to move outwardly and through their attached yokestraps withdraw the presser-rollers F from contact with the cylinder or drum G, it being of course understood that at such periods the pressure upon the plungers K in the cylinders L will be removed.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is#- l. In a machine for the purpose described, a central, rotatable, driven drum, a plurality ot' surrounding presserrollers situated on all sides of and supporting said drum, said rollers being rotated by said drurn and at the same speed by reason of their peripheral contact therewith.
